A new pizzeria charges $4.00 for a personal size cheese pizza. They then charge you $1.00 for each topping you choose to add to the pizza. Write an equation that represents the total cost of the pizza based on each additional topping. Is option 1 or 2 correct? Option 1: The equation of the additive relationship is y=x−4 . Option 2: The equation of the additive relationship is y=x+4 .

Answer 1

Option 2 is correct.

The total cost of the pizza is the base price of $4.00 plus $1.00 for each additional topping, so the equation representing this relationship would be:

y = x + 4

Where:
y = total cost of the pizza
x = number of toppings added
